Reply To: Module 5 – Rockets & Alien Chemistry

    One of the activities the pupils really enjoy is making Alien Slime or Space Slime as I have used a different method in the past and it was a great success with the older classes. The plan was as follows:
    Making Alien Slime
    Objective: Children will learn to create a fun, sensory “alien slime” while practising basic measurement skills and understanding simple chemical reactions.

    Materials Needed:- White school glue (1 cup) – Water (1 cup) – Liquid starch (1 cup) – Green food colouring – Glitter (optional) – Mixing bowls – Spoons – Measuring cups

    Introduction (5 minutes): – Discuss what slime is and why it’s fun to play with. – Introduce the concept of a chemical reaction in simple terms (mixing ingredients to make something new).

    Instructions (15 minutes):
    1. Measure and Pour: Help children measure and pour 1 cup of glue into a bowl.
    2. Add Water: Measure and add 1 cup of water to the glue. Mix well.
    3. Colour It: Add a few drops of green food colouring. Stir until evenly mixed.
    4. Add Liquid Starch: Measure and add 1 cup of liquid starch slowly while stirring. Watch the slime form!
    5. Optional – Add Glitter: Mix in glitter to make it sparkle.

    Activity (10 minutes): Let children knead the slime until it reaches the desired consistency. – Discuss the texture and how it feels.

    Conclusion (5 minutes): Clean up together. – Review the steps and talk about what they learned.

    Wrap-Up: – Take home the slime in a sealed bag.
